Capsule Endoscope Gyroscope Orientation Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional endoscopy procedures are invasive, uncomfortable, and costly, requiring sterile environments and general anesthesia, whereas a non-invasive capsule endoscopy system with an imaging capsule and external unit, equipped with a gyroscope to determine image orientation, allows for cost-effective and comfortable gastrointestinal tract imaging without anesthesia, reducing procedure costs and discomfort.
Innovation Solution
The capsule endoscopy system comprises an imaging capsule with a gyroscope to capture images from various orientations within the gastrointestinal tract and an external unit that aligns with the subject's body frame of reference, allowing image orientation determination and processing, enabling non-invasive imaging without the need for sterile environments or anesthesia.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional endoscopy procedures are used, then detailed internal imaging is achieved, but the procedure becomes invasive, requires anesthesia, and increases cost
Solution Approach 1:
The patent replaces the mechanical endoscope system with a magnetic resonance imaging system that uses magnetic fields and radio waves to image the gastrointestinal tract. The MRI system substitutes the physical insertion of an endoscope with non-invasive electromagnetic field-based imaging, eliminating the need for mechanical intrusion while maintaining diagnostic imaging capability
Solution Approach 2:
The patent changes the imaging parameters by using magnetic resonance imaging instead of optical imaging. By utilizing the magnetic properties of hydrogen nuclei in body tissues and applying radio frequency pulses, the system achieves internal imaging through non-invasive electromagnetic interactions rather than direct optical observation requiring physical insertion
2Measurement precision
If conventional endoscopy procedures are used, then internal imaging is achieved, but sterile environments and anesthesia are required
Solution Approach 1:
The patent replaces the complex mechanical endoscope insertion and manipulation system with a magnetic resonance imaging system. The MRI approach eliminates the need for sterile environments and anesthesia by using external magnetic fields and radio waves that can penetrate the body without physical intrusion, thereby simplifying the procedural requirements while maintaining imaging capability
Solution Approach 2:
The patent introduces magnetic fields and radio waves as intermediaries to achieve internal imaging without direct physical contact. These electromagnetic fields serve as mediators that can penetrate the body to image internal structures, replacing the need for physical endoscope insertion and the associated sterile and anesthesia requirements
3Object-affected harmful factors
If a capsule endoscopy system with gyroscope is used, then non-invasive imaging is achieved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into the capsule endoscopy system: the gyroscope provides orientation detection, the image capture device records gastrointestinal structures, and the wireless transmitter sends data externally. This multi-functional integration allows the single capsule device to perform navigation, imaging, and data transmission, managing complexity through functional consolidation rather than separate systems
Solution Approach 2:
The capsule system performs self-navigation and self-imaging by using the gyroscope to determine its own orientation and the image capture device to record images based on that orientation. The system serves itself by autonomously capturing images in the correct orientations without external control, reducing the need for complex external manipulation systems
4Measurement precision
If image orientation determination is implemented, then diagnostic accuracy is improved, but processing complexity increases
Solution Approach 1:
The patent determines image orientation using the gyroscope before final image processing and display. By pre-determining the orientation data and associating it with each captured image, the system prepares orientation information in advance, simplifying subsequent processing steps where the orientation data is already available for diagnostic analysis without requiring complex real-time processing

Function Achieved in This Case
